Definitions

  • the front end of the spindle projects forward from the case C a sufficient distance to enable manual engagement thereof and the ratchet means R is such that by manually engaging the front end portion of the spindle, the spindle and a fastener driven thereby can be manually turned relative to the remainder of the wrench structure to, for example, advance the fastener to fingertight set position, preparatory to tightening it.
  • the spindle 20 has a central polygonal through opening 22 in and through which the polygonal drive stem or shaft of a work-engaging tool, such as a drive socket, (not shown) positioned at and projecting freely from the back side of the case C can be releasably engaged.
